Taylor Swift has made a career of writing about her life, perhaps most notably, her (often very public) splits. Still, the singer, 23, admits that she's learning to take the ups and downs as they come.

"I mean, I know where I'll be on tour in two months, but no idea where I'm going to be mentally, emotionally, dreams, goals, wishes, hopes," she tells Wonderland magazine in its new issue. "I have no idea if I'm going to get married or be single forever or have a family or just be on my own."

If it's the latter, she concedes, life could take on a whole new meaning: "[I could] paint in a cottage by the ocean by myself!" she says. "I just have no idea and I'm kind of into that."

Still, the "We are Never, Ever Getting Back Together" singer admits that the end of a relationship (and hers have been with an enviable list of men, including John Mayer, Jake Gyllenhaal, Conor Kennedy and John Mayer) is "very complex."

"You're never feeling just sad," she notes. "Maybe you wake up and you feel sad and then you get angry, and then you feel like, 'I'm fine,' and then you feel confident, and then you feel a sense of doubt and then you're insecure. And then there's jealousy and then you're back to sad-and then you feel fine again."
